Finasteride

It does not make you stronger but finasteride is used in doping as a masking agent to make the detection of anabolic abuse impossible. Some bodybuilders use it to counter the hair loss by anabolic abuse.
Finasteride is currently used in medicine for the treatment of androgenetic hair loss (alopecia) and benign prostatic hyperperie (BPH). Since 2007, it has been offered by various generics producers and is available on the German market to get prescription.

Finasteride is used for the treatment of androgenetic alopecia (conditional hair loss) in men aged 18 to 41 years. It is a 5α reductase inhibitor and engages in the hormonal metabolism of the sex hormone testosterone in dihydrotestosterone (DHT).
